I noticed that too and took it to be an artifact from a different route. Not sure how it got stuck on Quinoot Point.
Of course winds and seas dictate every route's viability however you might consider passing by Joassa Channel and maybe camping along Seaforth Channel on Dufferin Island. Gale Passage is an interesting twist with tidal rapids at both ends. They can be minimized by transiting the passage near high slack. You still get some current but nothing scary and then carrying on to McMullin. If not Gale Passage then continuing to the Cape Swain at the NW corner of Athlone Island and down the outside to Cape Mark. There is an interesting camp site at Cape Mark but access can be tide dependent. Again, a stop at McMullin is worthwhile.
While some say that Goose has the best beaches in BC I'm not a huge fan. Goose sees a lot of traffic and shows the signs of individuals who eschew LNT practices and it sort of forces a long crossing of Queens Sound. I've never had an issue with Queens Sound but some of my friends have.
Becky's route did not extend across Hakai Passage to Calvert Island. Personally, I feel that a kayak trip to Hakai without spending time on Calvert Island is like a "40 degree day" (reference from "The Wire"). Calvert is a trip of it's own and I always try to include it in any Central Coast trip.
If you haven't found it yet consider taking a peek at Phillip Torren's blog here (
https://philiptorrens.com/). He has reports on lots of routes, writes in an entertaining fashion and I'm pretty sure that he has at least one report on a route that might be what you are looking for.
Here's another entertain read about 14 days in Hakai.
